Heterotardigrada
The class Heterotardigrada includes tardigrades (water bears) that have cephalic appendages and legs with four separate but similar digits or claws on each. 444 species have been described. Anatomy The anatomy of the reproductive system is an important defining feature in distinguishing the different groups of tardigrades. Heterotardigrades have gonoducts that open to the outside through a preanal gonopore, rather than opening into the rectum as in the only other confirmed class of tardigrades, the Eutardigrada. The third class, Mesotardigrada Mesotardigrada is one of three classes of tardigrades, consisting of a single species, ''Thermozodium esakii''. The animal reportedly has six claws of equal length at each foot. This species was described in 1937 by German zoologist Gilbert Rah ..., is represented by a single species known from a single specimen that is now lost, and the location from which that specimen was collected has since been destroyed by an earthquake, so its ...

Arthrotardigrada
Arthrotardigrada are an order of tardigrades, first described by Marcus in 1927. Families Arthrotardigrada consists of the following families Family (from la, familia) is a group of people related either by consanguinity (by recognized birth) or affinity (by marriage or other relationship). The purpose of the family is to maintain the well-being of its members and of society.

Neostygarctidae
''Neostygarctus'' is a genus of tardigrades. It is the only genus in the family Neostygarctidae. It was named and described by Grimaldi de Zio, D'Addabbo Gallo and Morone De Lucia in 1982. Species The genus includes three species: * ''Neostygarctus acanthophorus'' Grimaldi de Zio, D'Addabbo Gallo & Morone De Lucia, 1982 * ''Neostygarctus lovedeluxe'' Fujimoto & Miyazaki, 2013, named after a Stand from JoJo's Bizarre Adventure that was in turn named after an album by Sade Sade may refer to: People * Marquis de Sade (1740–1814), French aristocrat, writer, and libertine * Sade (singer) (born 1959, Helen Folasade Adu), British Nigerian musician and lead singer of the eponymous band * Sade Baderinwa (born 1969), WAB ...; the discoverers said that the "hairy appearance of the new species appears as if affected by the power of 'Love Deluxe'". * ''Neostygarctus oceanopolis'' Kristensen, Sørensen, Hansen & Zeppilli, 2015 References Further reading *Grimaldi de Zio, D'Addabbo ...

Tardigrade
Tardigrades (), known colloquially as water bears or moss piglets, are a phylum of eight-legged segmented micro-animals. They were first described by the German zoologist Johann August Ephraim Goeze in 1773, who called them Kleiner Wasserbär ("little water bear"). In 1777, the Italian biologist Lazzaro Spallanzani named them Tardigrada (), which means "slow steppers". They have been found in diverse regions of Earth's biospheremountaintops, the deep sea, tropical rainforests, and the Antarctic. Tardigrades are among the most resilient animals known, with individual species able to survive extreme conditions – such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation – that would quickly kill most other known forms of life. Tardigrades have survived exposure to outer space. There are about 1,300 known species in the phylum Tardigrada, a part of the superphylum Ecdysozoa consisting of animals th ...

Mesotardigrada
Mesotardigrada is one of three classes of tardigrades, consisting of a single species, ''Thermozodium esakii''. The animal reportedly has six claws of equal length at each foot. This species was described in 1937 by German zoologist Gilbert Rahm from a hot spring near Nagasaki, Japan. The inability of taxonomists to replicate Rahm's finding has cast doubt on the accuracy of the description, making ''T. esakii'', and by extension the entire class Mesotardigrada, a ''taxon inquirendum''. Taxonomic ambiguity The type specimen Rahm used as the basis of his description has either been lost or it was never preserved in the first place, which Grothman ''et al''. (2017) suggest is consistent with the lax taxonomic standards of the 1930s. Thus, re-examination of the original specimen is not possible. Complicating matters further, the type locality from which Rahm collected his specimen may have been destroyed by an earthquake and subsequent searches for additional specimens matching ...
